HAWKING-MACHINE.

SPECIFICATION forming part of Letters Patent No.. 673,182, dated April30, 1901.

Application filed January 14, 1901. Serial No. 43,277. (No modelfi Toall whom it may concern:

Be it known that I, WALTER TURNER, a subject of the Queen of GreatBritain, residing at Halifax, in the county of York, England,

have invented certain new and. useful Improvements in Hawking-Machinesof Indigo- Dye Vats, of which the following is a specification.

This invention relates to hawking-machines employed in indigo-dye vats;and its object is to prevent damage to piecespassing through suchhawking-machine when the latter is submerged in the liquor during theprocess of dyeing. This damage takes place from several causes, butparticularly when the ordinary strippers now employed for stripping thepiece from the rollers do not bear against the surface of the rollers.evenly across their whole width. Such uneven contact is often occasionedby wear of the stripper or the surface of the roller itself at someparticular part or from wear of the roller necks or bearings, or theedge of the stripper may be turned up or otherwise damaged, or somesolid substance may lodge between the stripper and roller in such amanner as to prevent the stripper acting upon the piece at that part.The result is that the piece becomes wedged between the stripper and theroller and on being removed from the vat is very often found to beseriously dam aged. Detection of the irregularity of the action of thestrippers is impossible on account of their submersion in the dye liquorduring the process of dyeing. With my improved strippersit is impossiblefor the piece to become damaged from the above causes. The piece uponpassing through the rollers is automatically stripped oi the same andfalls to the bottom of the vat, where it is laid in folds and againpassed over the scray-lags 3 is a plan view of parts of a hawking-machine with my improvements applied, mounted upon an indigo-dye vat. Fig.4 is a plan of my improved roller and strippers employed inhawking-machines of indigo-dye vats.

In con structing the fast and loose rollers A B of a hawking-machine Iform the same with a series of annular grooves Cof asuitable width andat regular distances apart. A correspondingnumberof metal bands orstrippers D are attached to the cross beams or bars E F of thescray-lags G and passed around the nipping side of the said rollers A Bwithin the aforesaid grooves O and are again attached to the oppositeside of the cross beams or bars aforesaid. The loose roller A is mountedin sliding bearings H and is kept in contact with the roller-B in fixedbearings by means of lovers J, pivoted at J, and springs K, the pressureor nip being adjusted or regulated by screwed rod L and nut orthumb-screw M. I also attach the cross-beam E of the back scray-lag tothe slide N, carrying the loose roller-bearings H, by means of bolts Nor the like, so that upon the roller A being moved away from roller Bfrom some cause or other the strippers D within the grooves G of suchroller are also moved simultaneously in a corresponding degree and so donot interfere with the feed action of such rollers or the passage of thecloth or the insertion of a fresh piece to be dyed. Both strippers androller move simultaneously either backward or for-.

ward for the purposes before described.

The strippers D are so placed within the annular grooves of the rollersthat while being stationary themselves they offer no impediment to thefree revolution of the latter when acted upon by the roller in fixedbeartoo often adheres to either one or the other and is then brought bysuch roller into contact with the strippers D, which remove or strip thesame from the roller in the manner shown in dotted linesat Fig. 2', whenit falls and is folded or laid and again passed between the rollerswithout possibility of damage. By

this construction of and arrangement of strips pers it is impossible forthe ,pieceto be damaged by the strippers in its passage between therollers. There is no possibility of the strippers getting out of order.-There is no grinding of the strippers against the rollers,

- the effect of which will be obvious, and the machine may be used withconfidence by the workman and at a great saving to the proprietor, Ialso preferably add an additional cross-bans to the front scray-lag,having a beveled or rounded surface placed so as to with a series ofcircumferential grooves, of a series of strippers arranged in the saidgrooves between the pair of rollers,substantially as set forth.

2. The combination, with a pair of nippingrollers, one of the saidrollers being provided with a seriesof circumferential grooves, and ascray-lag behind the said grooved roller; of a series of strippersformed of loops inserted in the said grooves between the rollers andhaving their end portions secured to the said scray-lag, substantiallyas set forth.

3. The combination, with a pair of nippingrollers each provided with aseries of circumferential grooves, and scray-lags arranged behind thesaid rollers, one of the said rollers and its scray-lag being slidablewith respect to the other roller; of strippers arranged in the said.grooves and secured to the scray-lags, substantially as set forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

WALTER TURNER.
